Have you bought Windows office?. I:E boxed.
Did you buy a key from the internet to use with office?.
If you bought the boxed version then you must delete it through the "Add and Remove" section BEFORE you load on your copy
If it will not remove itself through here then go into the registry:
Start > run. type in "regedit". When in go to "find", this will be in the "edit" section.
Click on the "find" box and another box opens. Type "office 2007" in the box and then click on "find next" button. The registry will now search for office, when it does just select "delete" or use the delete key on your keyboard, you will need to go slowly doing this because you might much up your machine if you go too fast. When something relates to the office in question just use your delete key on your keyboard, if it does/can not delete then just use the keys (on your keyboard) "CTRL + F" this will force the registry to keep on finding another section on the office in question so that you can delete the keys or the registry to it. But just go slowly, do not hurry. When all is done and dusted, reboot your computer. When you see the desktop load on your new version of office and then you are good to go.
Please post back if you have any more problems or questions.
